honestly i think people need to try a bit more, and also talk a bit more. during queens gauntlet you constantly had people complaining in the middle of the event that the bosses weren't being killed in the correct order and with the right amount of cambatants to each etc, but no one was organising or talking before the match started. people who want to lead raids, dungeons, completions etc, need to be willing to actually explain things to new people and old and not just expect them to have certain armour or knowledge etc, i regularly play pvp and so many players either don't learn to play the map or expect everyone to be playing the same 'meta' they read on the internet. well no, i just ignore those people. if they want to play a particular way they can ask politely before the match begins and not click the 'ready' button until they think the group is ready. i understand that it's a 'GAME' and that of course i have greater things to do and so should they lol.
so yeah people need to talk more, and expect others to talk more, ask questions and if someone wants to treat you like a noob and pretend you should know it all from some guide then ignore that person, they likely have very little going on in their life, we should pity them lol.
but also people need to try more, i had an experience once where someone asked how to dye their armour, if they had simply looked and tried to figure it out it would have taken them two seconds, but nope couldn't even try. i don't care if people think it's a little difficult to figure out, just try, strengthen that muscle, things are alot more intuitive than people want to accept.
